Kewline is a business messaging inbox that connects to a business's WhatsApp Business, Facebook Messenger, and Instagram Direct accounts. In order to provide this service, Kewline stores:
We do not receive, store, or process any WhatsApp, Facebook, or Instagram data from a business unless that business explicitly connected the channel and granted us the required permissions.
Businesses (and Meta-authorized users connected to those businesses) can delete their data in any of the three ways below. All are available at any time — no waiting period, no justification required.
Access tokens for that channel are invalidated and deleted immediately, and all message and contact data received from that channel is permanently deleted within 30 days.
This removes every connected channel, all conversations, contacts, team members, and settings. Permanent deletion is completed within 30 days.
This option works even if you have lost access to your Kewline account or if your business no longer uses the service.
You may also remove Kewline's permissions directly from your Meta account, which immediately terminates all access:
After removal, we will automatically stop all data retrieval and delete the associated stored data as described above.
If you are a customer who messaged a business that uses Kewline, the conversation data belongs to that business — please request deletion from the business directly. If the business cannot or will not handle the request, or if you believe your data is being misused, contact us at [email protected] with details, and we will escalate it through our contracted obligations.
Messages themselves — and copies of the conversation content that Meta stores on its own platforms (for example, your own WhatsApp chat history on your device) — are outside Kewline's control. To delete data held by Meta itself, use Meta's own account or privacy tools (e.g., Accounts Center for managing your information across WhatsApp, Facebook, and Instagram).
| Action | What is removed | Timeline |
|---|---|---|
| Channel disconnected (Option 1) | Channel tokens (instant), then stored messages & contacts from that channel | Token deletion: instant Data deletion: within 30 days |
| Workspace deleted (Option 2) | All channels, conversations, contacts, team members, workspace settings | Within 30 days |
| Email request (Option 3) | Whatever the scope of the verified request (a channel, a workspace, or a specific customer's data) | Within 30 days of verification |
| Access removed via Meta Business Integrations | Treated as a disconnection — tokens and channel data deleted | Instant / within 30 days |
| Encrypted backup residue | Rolling backups are fully purged | Within 90 days (maximum) |
| Non-deleted records | Invoices, transaction records, and support logs we must keep for legal, tax, or accounting purposes | Retained per legal requirement; anonymized after that |
In addition to these instructions, Kewline supports Meta's data deletion callback: if Meta forwards a signed data-deletion request while a user removes Kewline's permissions, we automatically process deletion of that user's stored data and respond with the required confirmation and status URL. If the callback is unavailable, this page serves as the instructions page referenced in our Meta app's Data Deletion Instructions URL setting.
